摘要:
为了得到不同通风条件和旅客行李条件下CRH1动车组一等座车厢的火源热释放速率的合理取值范围,以CRH1型动车组一等座车厢为研究对象,以锥形量热仪和大型量热仪测定的高速客车车体内材料和行李的燃烧性能为输入参数,运用FDS软件模拟6种火灾场景下车厢的火源热释放速率随时间的变化规律,分析了通风条件、火灾荷载密度、可燃物间距和行李重量对车厢火源热释放速率的影响。研究结果表明:在不考虑旅客行李时,各种通风条件下车厢最大火灾热释放速率在186-434MW之间; 在车门与车窗开启条件下,与不考虑旅客行李的情况比较,人均携带10、20kg行李时,火源热释放速率分别增加了1284、1538MW,增加的幅度分别为570%和684%。
Abstract:
In order to get the reasonable range of heat release rate in the firstclass compartment of CRH1 under the influence of passenger baggage and various ventilations, the FDS software was used to simulate variation law of heat release rate VS. time in the train compartment in six kinds of fire scenarios, then the influence of the ventilation, the fire load density, the spacing of combustible and the weight of passenger baggage on heat release rate were analyzed. During the simulating process, the firstclass compartment of CRH1 was taken as an example, and the combustion performance parameters of materials and baggage in the train compartment, measured by the cone calorimeter and large calorimeter, were used as the input data. The simulation results showed that, without considering the passenger baggage and in the conditions of various ventilations, the maximum heat release rate of the compartment is between 186 and 434MW; when the doors and windows are open, without considering the passenger baggage and in the conditions of 10kg and 20kg baggage per capita, the heat release rates separately increase by 1284MW and 1538MW, and the growthrates are 570% and 684% respectively.
